Coexistence of ferro-and antiferromagnetic interactions in a metal-organic radical-based(6,3)-helical network with large channels

摘要

A metal-organic open-framework with an unprecedented(6,3)-helical topology,large channels and mixed ferro-and antiferromagnetic interactions has been synthesized using a three-connecting tricarboxylic polychlorotriphenylmethyl radical and Co(II)ions.Rapid development in the self-assembly of transition metal ions and multitopic organic ligands has yielded a wide variety of one-,two-and three-dimensional metal-organic architectures that have specific properties.
